Thanks much. Last I saw one was $550 for that and that was several years back. Companies like Nissens and CSF were making all metal radiators (not sure if for a Solstice) but Nissens jumped ship and their stuff is utter crap now. CSF seems to also be entering the race to the bottom and discontinuing most of their better rads too.
For that much coin I can have a local shop custom make a brass-copper one.
